    Hello My Name is wilspeak

    Looks like the Jansno that someone else here just bought except it has spokes instead of cast wheels, . While the style doesn't appeal to me,these bikes are pretty inexpensive at under $700 and appear to run as fast as advertised based on youtube reviews. I wonder if that swing arm is going to...

    Where is the controller on this Walmart ebike?

    This reddit thread says you can solder a throttle to three terminals on the hyper circuit board. Read down to the bottom. Or you could just put in a different controller, which will cost you about $100 up, A 20A KT controller might give you a better feel on the pedal assist, Their color...

    Where is the controller on this Walmart ebike?

    If you can't find it in the frame, it's probably inside the battery cradle.

    Has anyone tried building a hub motor wheel with your rim? Is it complicated?

    Yes, I've done over a dozen wheels now. There is a learning curve which teaches you not to give up. If you persist, every wobble can be take out, It's not rocket science. Just patience. It wasn't about cost initially, I started because I had wanted a front motor in a fat tire rim, Bike shops...

    What controller to use on Jansno X50 750 watt with upgraded 52v 40 amp battery?

    You'll spin the motor a little faster with 52V, but you already have a 25A controller then, I saw some youtube reviews. That bike goes pretty fast with a small hubmotor. I don't see much gain.

    What controller to use on Jansno X50 750 watt with upgraded 52v 40 amp battery?

    A 48V controller will run on 52V. Just put on the battery and ride. Whats the current rating on the Jasno X50 controller now? I am guessing 20-22 amps? Maybe leave it alone, If you are going to change, buy a Jansno model form their web page. The motor you have will take 52V, but it looks too...

    With 125% tariffs, will the e-bike market die?

    If ebike prices were to double, of course the market world die, but that's not going to happen. He caved on electronics, even though Lutnick is still sputtering about them. I'm picking up a new phone this week anyway.

    Riding without the motor

    Walking around to the back of the big box lumber/lunchmeat store (they sell both) had me out of breath today. Rode the regular bike 4.4 miles today. Could have gone further, but It's a start.

    xt 30 connector voltage

    With 52V, 48V and 36V batteries, I use 52, 48, and 36 as the halfway points. Better be turned around and going home by then. If not, it better be downhill.

    xt 30 connector voltage

    Both my Lunaticks packs from 9 years ago still work though, That better not work, if the BMS is doing its job and has shut off the battery. Bad idea if the BMS lets it happen.. The insides might only be at 30V,

    What about best fat tire electric bikes in 2025?

    I see your location is asia, but your fat bike link is an obvious scam, If you think anyone here is going to buy this fake bike, we're not that dumb here in the USA. Most of us anyway, The other bike link is just a junky folding fat tire bike. But if you are serious about purchasing a fat...

    Help needed!

    Probably screws off like the endcaps on the Martian spacecraft from War of the Worlds. In this case, the guy untorqued the cover so he could fo it by hand. You will need a tool because when the motor turns a crank gear, it really tightens the plate, I've got a few AKM motors which also use...

    Front Bike Camera - Specifications

    I see that Nvreloader likes the Akaso V50. I cheaped out and got the EK7000 in 2023. It's image stabilization was not quite good enough and the view angle was wider than I wanted.

    Ampler Nova e-bike

    The simple calculation is to derate the advertised watt-hours by 20%. Then use your personal Wh/mile rating to figure range, For me, that number ranges between 8-10 WH/mile. For the 337WH 48V7AH battery in that ampoler, the advertised 336WH drops to 270WH, and I'm pretty surre I can get around...

    Time to change my bike?

    Lots of youtube battery hotshots could revive that Aventon. but more than a few might have a fire .Leave it be. You got five years out of it. If it were a better battery,it wouldn't have discharged itself so low that it stops charging, So what to do with an battery that won't charge? It's not...

    Electric Bike Battery Repair & Repacking

    I believe it's real. Per the Indigogo page, 577 backers kicked in $217K, and they were testing the first product a few months ago. They're not taking any further orders though, With a trade war here, who knows what will happen. The lattice should have keyed somehow so you can't put a cell in...

    Bikes in the Age of Tariffs

    How about the big picture, where after a tariff induced recession, the consumer hasn't enough money to proritize a bicycle, which is not a necessity but mainly recreational in the USA. After Covid went dormant, tens of thousands of bikes purchased in 2020 must sit unused in storage. Probably...

    Hubmotor works only in learning mode, Throttle changes the turning direction and more!

    Well, now you won't have a display anymore. You will need to figure out how the three speed switch works, or buy one of those switches to be able to have more than one speed. No, an S866 display won't work with a foreign controller. Designers have to agree on a command protocol, a command set...
